Reddit reviews Hydroplanet™ 600W Digital Ballast Dimmable HPS Mh Grow Light System Hood for Plants with XXXL 6inch Air Cooled Tube grow lights reflector (600W)

/u/henry_haberdasher gave some great advice so I'd say to follow what he said.

When reading yoru post I thought the same things:

• Your tent is bigger then you need (but might be good for expanding in the future).
  
  
• Don't buy that light, it's good for seedlings but not for the whole grow, I'd go with an HPS, or possibly LED but those are more money. I'd get something like this: https://www.amazon.com/HydroplanetTM-Digital-Ballast-Dimmable-reflector/dp/B01AU7QMMW (Personally I prefer Lumatek ballasts but you can shop around).
  
  
• I also have only done a DYI DWC - so you can get the bucket you were looking at and upgrade the airpump/airstone, or it would be really easy to build that yourself.
  
  
• For Training take a look here: http://www.growweedeasy.com/lst

No worries, happy to help.

I've really no idea how many can grow in there tbh man. It is good for upgrading but you've mentioned keeping it warm. So consider this.

Bigger tent means a bigger environment to control, this means more more kit in winter to warm it - probably 2 heaters chewing through electric at a rate of knots. In summer, bigger extraction, either one giant fan or two medium ones. Making sure air current is good with more column fans moving air around etc and of course your air intake fan bringing in the fresh air. Do you see where i'm going wth this? Not so much about height, that is good. It's the floor space that was too much. I don't think a tent you can walk around in would be a good thing in such a cold room. In this case - more space isn't always better. Of course, this is just my opinion.

If you want 4 autos in a tent then go with a more normal sized tent. It's easier to control the environment and still able to handle your plant load. At least that would be my approach to this man.

I don't know any videos i'm afraid. I'm sure there are tons on Youtube - it's a fairly standard practise. Don't cut a hole in the lid though, do it in the side of the pot. Read that guide I sent I the last post - here and it'll tell you it all. I know there are no pictures of it, but it explains the steps. Tons of other tutorials around though man.

Yeah man, you'll be needed a Hygrometer and a Thermometer. I bought one like this.

I've never grown HPS so don't have a light to recommend i'm afraid. Although /u/IdStillHitIt recommended one which looked good.
